Endoscope Body Materials: Medical-grade Metals and Polymers
Endoscope bodies need to balance flexibility and durability:
Medical-grade stainless steel: Used for rigid bodies, corrosion-resistant and easy to sterilize
Titanium alloy: Lightweight design, suitable for prolonged surgical use
Medical-grade plastic: Flexible outer layer of the endoscope, ensuring biocompatibility
Silicone coating: Reduces tissue friction, improving patient comfort
Core Materials of the Optical System
Imaging quality depends on these key materials:
Optical glass: High-transmittance lens assembly, ensuring clear images
Fiber optic bundle: Tens of thousands of glass fibers forming an image transmission bundle
CCD/CMOS chip: Miniature image sensor
LED array: Cold light source illumination system
Auxiliary Functional Materials
These materials make endoscopes smarter and safer:
Medical-grade silicone sealing ring: Waterproof and anti-fog design
Nano-hydrophobic coating: Prevents body fluid adhesion
Shape memory alloy: Support structure for rotatable lenses
Conductive silver paste: Flexible circuitry integrating electronic circuitry
